Microprocessor Systems

Microprocessor Systems, In addition to the inductor component wasteful electricity consumption can also occur because:

Unstable voltage

Voltage instability can lead to wastage of electrical energy. Voltage instability can be interpreted in a phase of larger, smaller or fluctuate against standard voltage. While the result improvidence electrical energy that then arises first heat so that it can cause damage to the equipment used insulators. To two shortened power in the winding insulation. Meanwhile, with the imbalance of 3% just increase the temperature of the motor that is operating at 18% from its original state. This will cause the noise of the motor at high speed. 


Harmonic

Harmonics that can cause heat, this occurs because of excessive electrical energy. Harmonics that could arise due to equipment such as computers, motor control etc. Harmonic voltage is a state of emergence of different periods with the period of the standard voltage. The period can be 180 Hz (3rd harmonic), 300 Hz (5th harmonic) and so on. Harmonics on transformers is more dangerous, it is because of current circulation caused excessive heat. So that it can reduce the ability of protective equipment that uses power line carrier as the detector under normal conditions.

To optimize the electrical energy consumption could be used in the form of artificial burdens LC equipped with microprocessor technology. So the accuracy and reliability in detecting the power quality can be obtained. Microprocessor serves to process the components that determine the quality of electric power: as the load balance between phases, harmonics and surges. If there is an imbalance between phase one with the other phase, then the microprocessor will command the burdens of LC to open or close for the current supplied to phase one, thus the difference between the phase currents with phase one the other does not exist. The number of L or C opened or closed depending on the load imbalance is detected by a microprocessor. Conditions detected harmonic can be eliminated by using LC filters.
